dev-arm, configs: Using _on_chip_memory for on chip memory
This patch is pulling the on-chip memory outside of the on_chip_devices
list.
The external interface will be more or less the same: configuration
scripts will still use the attachOnChipIO method; a new kw argument has
been added in order to store mem_ports.
We want to provide to on-chip memory the same mechanism used when
collecting on-chip dma ports. This is needed when using Ruby, since
we need to pass a non None mem_ports to prevent the bootmem to be
wired to the bus.
